Keith Urban, it turns out, was one of the few sober people at his show in Mansfield, Mass. on Saturday night.

According to Rolling Stone, 46 people were treated at the concert, while 22 of them were hospitalized. More than 50 people were taken into custody by police.

"In total, Fire and EMS attended to 46 medicals resulting in 22 transports mostly alcohol-related," Mansfield Police Chief Ron Sellon and Fire Chief Neil Boldrighini said in the statement. "The large number of medicals in a shortened time of approximately three hours caused the activation of a phase one EMS plan utilizing ambulances from five mutual aid communities. Police dealt with a steady stream of intoxicated persons as well, resulting in over 50 people being taken into protective custody and a number of others arrested for alcohol-related issues."
